Nectarine tree--N15500

ABSTRACT

A nectarine tree which is large, vigorous, upright when young and spreading at maturity; foliated with medium size, lanceolate, dark green leaves having a broadly crenate margin and medium size, reniform, uniform, alternate stem glands; blooms from hardy, conic flower buds of medium size and length, the bloom time being medium compared with other varieties and very similar to Flamekist; the flowers being abundant, large, light pink, and showy; and is a regular and productive bearer of late-ripening, large, uniform, clingstone fruit nearly round to ovate in lateral aspect and globose in axial aspect; the fruit having red-blushed-over-yellow, glossy skin, yellow flesh, and a dark brown stone.

BACKGROUND OF THE VARIETY

1. Field of the Invention

In the operation and maintenance of a ranch--of which I am an owner--located near Fresno, Fresno County, Calif., I frequent such ranch for the purpose of inspection, soil cultivation, irrigation, and harvesting. Against the background of such activities, and during a harvest period, the present variety of nectarine tree was discovered by me.

2. Classification of the Variety

The present variety of nectarine tree is embraced by Class 41, Plants, of the U.S. Patent Office Manual of Classification.

3. Prior Varieties

Among existing varieties of nectarine trees which are known to me, and mentioned herein, is the Flamekist (unpatented).

ORIGIN OF THE VARIETY

The present variety of nectarine tree was discovered by me growing--as a mutation involving an entire tree--in an orchard of Flamekist nectarine trees on the aforesaid ranch. More particularly, I observed, during harvest, that a tree in such orchard (and which is the present variety) bore certain new and distinct characteristics, especially in relation to the appearance and ripening period of the fruit. Subsequently, under close and continuing observation of such singular tree, I confirmed such characteristics and determined to asexually reproduce the tree in anticipation of commercial growing thereof.

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety of nectarine tree was asexually reproduced, on the aforesaid ranch and under my direction, by grafting onto peach rootstock, and, in maturity, trees so reproduced ran true to the original tree (mutation) in all respects.

SUMMARY OF THE VARIETY

The present variety of nectarine tree is, characteristically, large, vigorous, upright when young and spreading at maturity; foliated with medium size lanceolate, dark green leaves having a broadly crenate margin and medium size, reniform, uniform, alternate stem glands; blooms from hardy, conic flower buds of medium size and length, the bloom time being medium compared with other varieties and very similar to Flamekist; the flowers being abundant, large, light pink, and showy; and is a regular and productive bearer of late-ripening, large, uniform, clingstone fruit nearly round to ovate in lateral aspect and globose in axial aspect; the fruit having red-blushed-over-yellow, glossy skin, yellow flesh, and a dark brown stone.

The present variety of nectarine tree is further characterized by the later maturity of the fruit in comparison to the Flamekist. On the aforesaid ranch, and as exemplary, the first picking and last picking of the fruit of the Flamekist were, respectively, Aug. 12, 1982, and Aug. 26, 1982, whereas the first picking and the last picking of the fruit of the present variety were, respectively, Aug. 24, 1982, and Sept. 3, 1982. This is indicative that the present variety of nectarine tree is about twelve days later, in fruit maturity, than the Flamekist.

The present variety of nectarine tree is still further characterized by fruit having discernibly more red blush than the Flamekist. As grown on the aforesaid ranch, the Flamekist bears fruit which--at commercial maturity--averages fifteen to twenty percent red blush at best, and at worst is full yellow, whereas the present variety bears fruit which--at commercial maturity--averages fifty to seventy-five percent red blush at best, and at worst thirty percent red blush. Additionally, the fruit of the present variety has more skin wax in comparison with the Flamekist, and which--together with the enhanced red blush--imparts to the fruit a brighter, glossier overall external finish and appearance.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is an illustration, by photographic reproduction in color, of separate fruit of the present variety; one such fruit being half cut away to expose the flesh, and with the stone remaining in place.

RESISTANCE TO INSECTS AND DISEASES

No unusual susceptibilities noted.

The nectarine tree and its fruit herein described may vary in slight detail due to climatic and soil conditions under which the variety may be grown; the present description being of the variety as grown in the Central Valley of California. 

I claim:
 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, particularly characterized, in comparison with the Flamekist, by late-ripening, clingstone fruit which, at commercial maturity, has more red blush and more skin wax, whereby the fruit has a brighter, glossier overall external finish and appearance.
